I use the mystic Razor jacket, does a good job not to bulky, gives some support, extra layer in winter and hepls with wind chill. No loose bits that get in the way, works with my Mystic Warrior waist harness and is good for using as impact vest too.

the treasure looks cooler so get that one
I use an impact vest and want to upgrade mine. But I am going to wait till i can try some on at the expo. The Mystic ones look nice, and never thought about them until now. I like the ION vests on paper, but they are mainly a European company i think
